GT
1. Short for Greater Than, GT is an operator represented as an arrow pointing to the right ( > ) and is used in programming, commands, and in mathematics.
if ($value1 > $value2) {
do this;
}
In the above example, if value1 is greater than value2, it would perform the operation do this. Otherwise, it would continue through the program.
The wide edge of the greater than symbol always faces the larger number. So
with 5 > 1 it's easy to see five is greater than one.
2. GT is also short for Greenwich Mean Time.
